24LC08BHT-I/ST

Memory IC Overview

The Microchip Technology 24LC08BHT-I/ST is an 8 Kbit Electrically Erasable PROM organized as four blocks of 256 x 8-bit memory. It features a 2-Wire Serial Interface compatible with I2C™, supporting maximum clock frequencies of 100 kHz and 400 kHz. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V. It utilizes low-power CMOS technology with a maximum active read current of 1 mA and standby current of 1 µA. The component includes hardware write-protect functionality for half the array and offers data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware Write-Protect: Enables protection of the upper half of the memory array via the WP pin.
• Page Write Capability: Supports writing up to 16 bytes of data simultaneously using an internal page buffer.
• Noise Suppression: Incorporates Schmitt Trigger inputs and output slope control to minimize ground bounce and noise interference.

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in sensor modules

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to the specific reel packaging configuration required for automated assembly processes. Confirm the 'I' temperature grade aligns with the operational environmental limits of the target application. Ensure compatibility with the host controller's I2C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when half-array write protection is necessary to prevent accidental modification of critical data. The TSSOP package is suitable for space-constrained surface mount designs. Consider the 400 kHz speed capability if higher bus throughput is required compared to standard 100 kHz devices.

Memory IC Part Context

This part belongs to the 24AA08H/24LC08BH family of 8 Kbit serial EEPROMs. It shares architectural similarities with other members but is distinguished by its specific voltage range and package type. The 'L' designation indicates operation down to 2.5 V, differentiating it from lower-voltage variants within the same product line.

Memory IC Replacement Considerations

Direct substitutes include the 24LC08BH-I/ST for tube packaging or the 24LC08BT-I/ST for cut tape options. Verify that alternative packages maintain identical pinout configurations and electrical characteristics.
